95% of the time I keep it at 4200 rpm or lower. Currently at 300 miles. A few times I had to bump it up to 5800 to pass someone or pop onto the interstate. Once I took it to 7000+ to prove a point. Is the rpm limit a guide to follow most of the time or all of the time? I iknow the motor wont blow up and its better to observe the guide lines of the break-in rules. But 1000 miles of babying is difficult.
